Introduction SSL / IPSec VPN QoS Router (referred as VPN Router hereby) is a business level security router that efficiently integrates new generation multiple WAN-port devices. It meets the needs of medium enterprises, internet cafés, campus, dorm and communities, etc. Apart from its internet connectivity that suits the broadband market, VPN Router has a built-in QoS and VLAN switching board which enables it to fulfill most enterprise and internet cafe firewall needs. VPN Router has 2 10/100 Base-T/TX Ethernets (RJ45) WAN ports. These WAN ports can support auto load balance mode, exclusive mode (remaining WAN balance), and stategy routing mode for high-efficiency network. They offer super flexibility for network set-up. Moreover, these WAN ports also support DHCP, fixed IP, PPPoE, transparent bridge, VPN connection, port binding, static routing, dynamic routing, NAT, one to one NAT, PAT, MAC Clone, as well as DDNS. As for LAN ports including one DMZ, they support 4 10/100 Base-T/TX Ethernet (RJ45) ports and provide the features of Microsoft UPnP, VLAN, Multi Subnet, and transparent bridge mode. Internet IP addresses can also be used in intranet. To fulfill the requirement for a highly secure and integrated firewall, VPN Router has a 64-bit hardware acceleration, high-speed, high-efficiency processor embedded. With high processing speed, plusing high standard SDRAM and Flash, VPN Router brings users super networking efficiency. Its processing speed and capacity are almost equal to those of expensive enterprise-level VPN Routers. This is why the device is so popular with modern enterprises. In addition to internet connectability, for the broadband market, VPN Router has the function of VPN virtual network connection. It is equipped with a virtual private network hardware acceleration mode which is widely used in modern enterprises, and offers full VPN functionality. Qno is a supporter of the IPSec and SSL Protocol. IPSec/SSL VPN provides DES, 3DES, AES-128 encryption, MD5, SH1 certification, IKE Pre-Share Key, or manual password interchange. VPN Router also supports aggressive mode. When a connection is lost, VPN Router will automatically re-connect. In addition, the device features NetBIOS transparency, and supports IP grouping for connections between clients and host in the virtual private network. VPN Router offers the function of a standard PPTP server, which is equipped with connection setting status. Each WAN port can be set up with multiple DDNS at the same time. It is also capable of establishing VPN connections with dynamic IP addresses. VPN Router also has unique QVM VPN- SmartLink IPSec VPN. Just input VPN server IP, user name, and password, and IPSec VPN will be automatically set up. Through VPN Router exclusive QVM function, users can set up QVM to work as a server, and have it accept other QVM series products from client ports. QVM offers easy VPN allocation for users; users can do it even without a network administrator. VPN Router enables enterprises to benefit from VPN without being troubled with technical and network management problems. The central control function enables the host to log in remote client computers at any time. Security and secrecy are guaranteed to meet the IPSec standard, so as to ensure the continuity of VPN service. The advanced built-in firewall function enables VPN Router to resist most attacks from the Internet. It utilizes active detection technology SPI (Stateful Packet Inspection). The SPI firewall functions mainly within the network by dynamically inspecting each link. The SPI firewall also has a warning function for 1 SSL / IPSec VPN QoS Router the application process; therefore, it can refuse links to non-standard communication protocols. VPN Router supports network address translation (NAT) function and routing modes. It makes the network environment more flexible and easier to manage. Through web- based UI, VPN Router enables enterprises to have their own network access rules . To control web access, users can build and edit filter lists. It also enables users to ban or monitor websites according to their needs. By the filter setting and complete OS management, school and business internet management will be clearly improved. VPN Router offers various on-line SysLog records. It supports on-line management setup tools; it makes setting up networks easy to understand.

Router Plus NAT Mode： When you apply a public IP address as your default gateway, you can setup this public IP address into a LAN PC, and this PC can use this public IP address to reach the Internet. Others PCs can use NAT mode to reach the Internet. If this WAN network is enabled the Router plus NAT mode, you can still use load balancing function in this WAN network. 31 SSL / IPSec VPN QoS Router WAN IP address Enter the public IP address. Subnet mask Enter the public IP address subnet mask. WAN Default Gateway Enter the WAN default gateway, which provided by your ISP. DNS Servers Enter the DNS server IP address, you must have to enter a DNS server IP address, maximum two DNS servers IP addresses available.. LAN Default Gateway Enter one of IP addresses that provide by the ISP as your default gateway. 32 SSL / IPSec VPN QoS Router LAN IP Addresses Range Enter your IP addresses range, which IP addresses are provided by ISP. If you have multiple IP ranges, you need setup group1 and group 2. You can also setup the default gateway and IP range in the group 2. DMZ Setting For some network environments, an independent DMZ port may be required to set up externally connected servers such as WEB and Mail servers. Therefore, the device supports a set of independent DMZ ports for users to set up connections for servers with real IP addresses. The DMZ ports act as bridges between the Internet and LANs. IP address: Indicates the current default static IP address. Config.: Indicates an advanced configuration modification: Click Edit to enter the advanced configuration page. The DMZ configuration can be classified by Subnet and Range: Subnet： The DMZ and WAN located in different Subnets For example: If the ISP issued 16 real IP addresses: 220.243.230.1-16 with Mask 255.255.255.240, users have to separate the 16 IP addresses into two groups: 220.243.230.1-8 with Mask 255.255.255.248, and 220.243.230.9-16 with Mask 255.255.255.248 and then set the device and the gateway in the same group with the other group in the DMZ. 33 SSL / IPSec VPN QoS Router Range： DMZ and WAN within same Subnet IP Range: Input the IP range located at the DMZ port. After the changes are completed, click “Apply” to save the configuration, or click “Cancel" to leave without making any changes. DMZ IP ranges are the same with WAN IP ranges in Router Plus NAT mode： 34 SSL / IPSec VPN QoS Router LAN Default Gateway Enter the LAN Default Gateway that you configured at Router Plus NAT Mode LAN IP Range Enter the usable static IP range that provide by ISP into the DMZ service IP range. If you have other IP range, you can setup the default gateway and IP range into group 2. After the changes are completed, click “Apply” to save the configuration, or click “Cancel" to leave without making any changes. 35 SSL / IPSec VPN QoS Router 6.2 Multi- WAN Setting When you have multiple WAN gateways, you can use Traffic Management and Protocol Binding function to fulfill WAN road balancing, so that we can have highest network bandwidth efficiency. 36 SSL / IPSec VPN QoS Router 6.2.1 Load Balance Mode Auto Load Balance Mode When Auto Load Balance mode is selected, the device will use sessions or IP and the WAN bandwidth automatically allocate connections to achieve load balancing for external connections. The network bandwidth is set by what users input for it. For example, if the upload bandwidth of both WANs is 512Kbit/sec, the automatic load ratio will be 1:1; if one of the upload bandwidths is 1024Kbit/sec while the other is 512Kbit/sec, the automatic load ratio will be 2:1. Therefore, to ensure that the device can balance the actual network load, please input real upload and download bandwidths. Session Balance: If “By Session” is selected, the WAN bandwidth will automatically allocate connections based on session number to achieve network load balance. IP Session Balance: If “By IP” is selected, the WAN bandwidth will automatically allocate connections based on IP amount to achieve network load balance. Note! For either session balancing or IP connection balancing, collocation with Protocol Binding will provide a more flexible application for bandwidth. Users can assign a specific Intranet IP to go through a specific service provider for connection, or assign an IP for a specific destination to go through the WAN users assign to connect with the Internet. For example, if users want to assign IP 192.168.1.100 to go through WAN 1 when connecting with the Internet, or assign all Intranet IP to go through WAN 2 when connecting with servers with port 80, or assign all Intranet IP to go through WAN 1 when connecting with IP 211.1.1.1, users can do that by configuring “Protocol Binding”. Attention! When the Auto Load Balance mode is collocated with Protocol Binding, only IP 37 SSL / IPSec VPN QoS Router addresses or servers that are configured in the connection rule will follow the rule for external connections; those which are not configured in the rule will still follow the device Auto Load Balance system. Please refer to the explanations in 6.2.3 Configuring Protocol Binding for setting up Protocol Binding and for examples of collocating router modes with Protocol Binding. Specify WAN Binding Mode This mode enables users to assign specific intranet IP addresses, destination application service ports or destination IP addresses to go through an assigned WAN for external connection. After being assigned, the specific WAN will only support those assigned Intranet IP addresses, specific destination application service ports, or specific destination IP addresses. Intranet IP, specific destination application service ports and specific destination IP that is not configured under the rules will go through other WANs for external connection. For unassigned WANs, users can select Load Balance mode and select session or IP for load balancing. ● Session Balance: If “By Session” is selected, the WAN bandwidth will automatically allocate connections based on session number to achieve network load balance. ● IP Balance: If “By IP” is selected, the WAN bandwidth will automatically allocate connections based on the number of IP addresses to achieve network load balance. Note! Only when a device assignment is collocated with Protocol Binding can the balancing function be brought into full play. For example, an assignment requiring all Intranet IP addresses to go through WAN 1 when connecting with service port 80, or go through WAN 1 when connecting with IP 211.1.1.1, must be set up in the Protocol Binding Configuration. Attention: When assigning mode is selected, as in the above example, the IP(s) or service provider(s) configured in the connection rule will follow the rule for external connections, but those which are not configured in the rule will still follow the device Load Balance system to go through other WAN ports to connect with the Internet. Please refer to the explanations in 6.2.3 Configuring Protocol Binding for setting up Protocol Binding and for examples of collocating router mode with Protocol Binding. Strategy Routing Mode If strategy Routing is selected, the device will automatically allocate external connections based on 38 SSL / IPSec VPN QoS Router routing policy (Division of traffic between Telecom and Netcom is to be used in China) embedded in the device. All you have to do is to select the WAN (or WAN group) which is connected with Netcom; the device will then automatically dispatch the traffic for Netcom through that WAN to connect with the Internet and dispatch traffic for Telecom to go through the WAN connected with Telecom to the Internet accordingly. In this way, the traffic for Netcom and Telecom can be divided. Set WAN Grouping: If more than one WAN is connected with Netcom, to apply a similar division of traffic policy to these WANs, a combination for the WANs must be made. Click “Set WAN Grouping”; an interactive window as shown in the figure below will be displayed. Name: To define a name for the WAN grouping in the box, such as “Education” etc. The name is for recognizing different WAN groups. Interface: Check the boxes for the WANs to be added into this combination. Add To List: To add a WAN group to the grouping list. Delete selected: To remove selected WANs from the WAN grouping. Apply: Click “Apply” to save the modification. 39 SSL / IPSec VPN QoS Router Cancel: Click “Cancel” to cancel the modification. This only works before “Apply” is clicked. After the configuration is completed, in the China Netcom Policy window users can select WANs in combination to connect with Netcom. Import Strategy: A division of traffic policy can be defined by users too. In the “Import Strategy” window, select the WAN or WAN group (ex. WAN 1) to be assigned and click the “Import IP Range” button; the dialogue box for document importation will be displayed accordingly. A policy document is an editable text document. It may contain a destination IP users designated. After the path for document importation has been selected, click “Import”, and then at the bottom of the configuration window click “Apply”. The device will then dispatch the traffic to the assigned destination IP through the WAN (ex. WAN 1) or WAN grouping users designated to the Internet. To build a policy document users can use a text-based editor, such as Notepad, which is included with Windows system. Follow the text format in the figure below to key in the destination IP addresses users want to assign. For example, if the destination IP address range users want to designate is 140.115.1.1 ~ 140.115.1.255, key in 140.115.1.1 ~ 140.115.1.255 in Notepad. The next destination IP address range should be keyed in the next line. Attention! Even if only one destination IP address is to be assigned, it should follow the same format. For example, if the destination IP address is 210.66.161.54, it should be keyed in as 210.66.161.54~210.66.161.54. After the document has been saved (the extension file name is .txt), users can import the IP range of self-defined strategy. 40 SSL / IPSec VPN QoS Router Note! China Netcom strategy and self-defined strategy can coexist. However, if a destination IP is assigned by both China Netcom strategy and self-defined strategy, China Netcom strategy will take priority. In other words, traffic to that destination IP will be transmitted through the WAN (or WAN group) under China Netcom strategy. 6.2.2 Network Service Detection This is a detection system for network external services. If this option is selected, information such “Retry” or “Retry Timeout” will be displayed. If two WANs are used for external connection, be sure to activate the NSD system, so as to avoid any unwanted break caused by the device misjudgment of the overload traffic for the WAN. 41 SSL / IPSec VPN QoS Router Interface: Select the WAN Port that enables Network Service Detection. Retry: This selects the retry times for network service detection. The default is five times. If there is no feedback from the Internet in the configured “Retry Times", it will be judged as “External Connection Disconnected”. Retry Timeout: Delay time for external connection detection latency. The default is 30 seconds. After the retry timeout, external service detection will restart. When Fail: (1) Generate the Error Condition in the System Log: If an ISP connection failure is detected, an error message will be recorded in the System Log. This line will not be removed; therefore, the some of the users on this line will not have normal connections. This option is suitable under the condition that one of the WAN connections has failed; the traffic going through this WAN to the destination IP cannot shift to another WAN to reach the destination. For example, if users want the traffic to 10.0.0.1 ~ 10.254.254.254 to go only through WAN1, while WAN2 is not to support these destinations, users should select this option. When the WAN1 connection is disconnected, packets for 10.0.0.1~10.254.254.254 cannot be transmitted through WAN 2, and there is no need to remove the connection when WAN 1 is disconnected. (2) Keep System Log and Remove the Connection: If an ISP 42 SSL / IPSec VPN QoS Router connection failure is detected, no error message will be recorded in the System Log. The packet transmitted through this WAN will be shifted to the other WAN automatically, and be shifted back again when the connection for the original WAN is repaired and reconnected. This option is suitable when one of the WAN connections fails and the traffic going through this WAN to the destination IP should go through the other WAN to reach the destination. In this way, when any of the WAN connections is broken, other WANs can serve as a backup; traffic can be shifted to a WAN that is still connected. Detecting Feedback Servers: Default Gateway: The local default communication gateway location, such as the IP address of an ADSL router, will be input automatically by the device. Therefore, users just need to check the option if this function is needed. Attention! Some gateways of an ADSL network will not affect packet detection. If users have an optical fiber box, or the IP issued by ISP is a public IP and the gateway is located at the port of the net café rather than at the IP provider’s port, do not activate this option. ISP Host: This is the detected location for the ISP port, such as the DNS IP address of ISP. When configuring an IP address for this function, make sure this IP is capable of receiving feedback stably and speedily. (Please input the DNS IP of the ISP port) Remote Host: This is the detected location for the remote Network Segment. This Remote Host IP should better be capable of receiving feedback stably and speedily. (Please input the DNS IP of the ISP port). DNS Lookup Host: This is the detect location for DNS. (Only a web address such as www.hinet.net is acceptable here. Do not input an IP address.) In addition, do not input the same web address in this box for two different WANs. Note！ In the load balance mode for Assigned Routing, the first WAN port (WAN1) will be saved for the traffic of the IP addresses or the application service ports that are not assigned to other WANs (WAN2). 43 SSL / IPSec VPN QoS Router Therefore, in this mode, we recommend assigning one of the connections to the first WAN. When other WANs (WAN2) are broken and connection error remove (Remove the Connection) has been selected for the connection detection system, traffic will be shifted to the first WAN (WAN1). In addition, if the first WAN (WAN1) is broken, the traffic will be shifted to other WANs in turn. For example, the traffic will be shifted to WAN2. 6.2.3 Protocol Binding Interface Configuration Router allows maximum four WAN interface, the bandwidth and real connection of every WAN will impact the load balance mechanism; therefore you need to set the Bandwidth and the Network service detection by each WAN Port correctly. In “Interface Configuration”, click “Edit” to enter the WAN port configuration. Bandwidth Configuration When Auto Load Balance mode is selected, the device will select sessions or IP and the WAN bandwidth will automatically allocate connections to achieve load balancing for external connections. The network bandwidth is set by what users input for it. For example, if the upload bandwidth of both WANs is 512Kbit/sec, the automatic load ratio will be 1:1; if one of the upload bandwidths is 1024Kbit/sec, while the other is 512Kbit/sec, the automatic load ratio will be 2:1. Therefore, to ensure that the device can balance the actual network load, please input real upload and download bandwidths. The section refers to QoS configuration. Therefore, it should be set in QoS page. Please refer to 8.1 QoS bandwidth configuration. 44 SSL / IPSec VPN QoS Router Protocol Binding Users can define specific IP addresses or specific application service ports to go through a user-assigned WAN for external connections. For any other unassigned IP addresses and services, WAN load balancing will still be carried out. Note！ In the load balance mode of Assigned Routing, the first WAN (WAN1) cannot be assigned. It is to be saved for the IP addresses and the application Service Ports that are not assigned to other WANs (WAN2) for external connections. In other words, the first WAN (WAN1) cannot be configured with the Protocol Binding rule. This is to avoid a condition where all WANs are assigned to specific Intranet IP or Service Ports and destination IP, no more WAN ports will be available for other IP addresses and Service Ports. 45 SSL / IPSec VPN QoS Router Service: This is to select the Binding Service Port to be activated. The default (such as ALL-TCP&UDP 0~65535, WWW 80~80, FTP 21 to 21, etc.) can be selected from the pull-down option list. The default Service is All 0~65535. Option List for Service Management: Click the button to enter the Service Port configuration page to add or remove default Service Ports on the option list. Source IP: Users can assign packets of specific Intranet virtual IP to go through a specific WAN port for external connection. In the boxes here, input the Intranet virtual IP address range; for example, if 192.168.1.100~150 is input, the binding range will be 100~150. If only specific Service Ports need to be designated, while specific IP designation is not necessary, input “0” in the IP boxes. Dest. IP: In the boxes, input an external static IP address. For example, if connections to destination IP address 210.11.1.1 are to be restricted to WAN1, the external static IP address 210.1.1.1 ~ 210.1.1.1 should be input. If a range of destinations is to be assigned, input the range such as 210.11.1.1 ~ 210.11.255.254. This means the Class B Network Segment of 210.11.x.x will be restricted to a specific WAN. If only specific Service Ports need to be designated, while a specific IP destination assignment is not required, input “0” into the IP boxes. Interface: Select the WAN for which users want to set up the binding rule. Enable: To activate the rule. Add To List: To add this rule to the list. Delete selected To remove the rules selected from the Service List. item: Moving Up & The priority for rule execution depends on the rule order in the list. A rule Down: located at the top will be executed prior to those located below it. Users can arrange the order according to their priorities. Note！ The rules configured in Protocol Binding will be executed by the device according to their priorities too. The higher up on the list, the higher the priority of execution. 46 SSL / IPSec VPN QoS Router Show Priority： Click the “Show Table” button. A dialogue box as shown in the following figure will be displayed. Users can choose to sort the list by priorities or by interface. Click “Refresh” and the page will be refreshed; click “Close” and the dialogue box will be closed. Add or Remove Service Port If the Service Port users want to activate is not in the list, users can add or remove service ports from “Service Management” to arrange the list, as described in the following： Service Name: In this box, input the name of the Service Port which users want to activate, such as BT, etc. Protocol: This option list is for selecting a packet format, such as TCP or UDP for the Service Ports users want to activate. Port range: In the boxes, input the range of Service Ports users want to add. 47 SSL / IPSec VPN QoS Router Add To List: Click the button to add the configuration into the Services List. Users can add up to 100 services into the list. Delete selected To remove the selected activated Services. service: Apply: Click the “Apply” button to save the modification. Cancel: Click the “Cancel” button to cancel the modification. This only works before “Apply” is clicked. Exit: To quit this configuration window. Auto Load Balancing mode when enabled： The collocation of the Auto Load Balance Mode and the Auto Load Mode will enable more flexible use of bandwidth. Users can assign specific Intranet IP addresses to specific destination application service ports or assign specific destination IP addresses to a WAN users choose for external connections. Example 1：How do I set up Auto Load Balance Mode to assign the Intranet IP 192.168.1.100 to WAN2 for the Internet? 48 SSL / IPSec VPN QoS Router As in the figure below, select “All Traffic” from the pull-down option list “Service”, and then in the boxes of “Source IP” input the source IP address “192.168.1.100” to “100”. Retain the original numbers “0.0.0.0” in the boxes of “Destination IP” (which means to include all Internet IP addresses). Select WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. Example 2：How do I set up Auto Load Balance Mode to keep Intranet IP 192.168.1.150 ~ 200 from going through WAN2 when the destination port is Port 80? As in the figure below, select “HTTP [TCP/80~80]” from the pull-down option list “Service”, and then in the boxes for “Source IP” input “192.168.1.150” to “200”. Retain the original numbers “0.0.0.0” in the boxes of “Destination IP” (which means to include all Internet IP addresses). Select WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. 49 SSL / IPSec VPN QoS Router Example 3：How do I set up Auto Load Balance Mode to keep all Intranet IP addresses from going through WAN2 when the destination port is Port 80 and keep all other services from going through WAN1? As in the figure below, there are two rules to be configured. The first rule: select “HTTP [TCP/80~80]” from the pull-down option list “Service”, and then in the boxes of Source IP input “192.168.1.0” to “0” (which means to include all Intranet IP addresses). Retain the original numbers “0.0.0.0” in the boxes of “Destination IP” (Which means to include all Internet IP addresses). Select WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. The device will transmit packets to Port 80 through WAN2. However, with only the above rule, packets that do not go to Port 80 may be transmitted through WAN2; therefore, a second rule is necessary. The second rule: Select “All Ports [TCP&UDP/1~65535]” from the pull-down option list “Service”, and then input “192.168.1.2 ~ 254” in the boxes of “Source IP”. Retain the original numbers “0.0.0.0” in the boxes of “Destination IP” (which means to include all Internet IP addresses). Select WAN1 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. The device will transmit packets that are not going to Port 80 to the Internet through WAN1. 50 SSL / IPSec VPN QoS Router Configuring “Assigned Routing Mode” for load Balance： IP Group: This function allows users to assign packets from specific Intranet IP addresses or to specific destination Service Ports and to specific destination IP addresses through an assigned WAN to the Internet. After being assigned, the specific WAN will only support those assigned Intranet IP addresses, destination Service Ports, or destination IP addresses. Those which are not configured will go through other WANs for external connection. Only when this mode is collocated with “Assigned Routing” can it bring the function into full play. Example 1：How do I set up the Assigned Routing Mode to keep all Intranet IP addresses from going through WAN2 when the destination is Port 80, and keep all other services from going through WAN1? As in the figure below, select “HTTP[TCP/80~80]” from the pull-down option list “Service”, and then in the boxes of “Source IP” input “192.168.1.0 ~ 0” (which means to include all Intranet IP addresses). Retain the original numbers “0.0.0.0” in the boxes of “Destination IP” (Which means to include all Internet IP addresses). Select WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. After the rule is set up, only packets that go to Port 80 will be transmitted through WAN2, while other traffics will be transmitted through WAN1. 51 SSL / IPSec VPN QoS Router Example 2：How do I configure Protocol Binding to keep traffic from all Intranet IP addresses from going through WAN2 when the destinations are IP 211.1.1.1 ~ 211.254.254.254 as well as the whole Class A group of 60.1.1.1 ~ 60.254.254.254, while traffic to other destinations goes through WAN1? As in the following figure, there are two rules to be configured. The first rule: Select “All Port [TCP&UDP/1~65535]” from the pull-down option list “Service”, and then in the boxes of “Source IP” input “192.168.1.0 ~ 0” (which means to include all Intranet IP addresses). In the boxes for “Destination IP” input “211.1.1.1 ~ 211.254.254.254”. Select WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. The second rule: Select “All Port [TCP&UDP/1~65535]” from the pull-down option list “Service”, and then in the boxes of “Source IP” input “192.168.1.0 ~ 0” (which means to include all Intranet IP addresses). In the boxes of “Destination IP” input “211.1.1.1 ~ 60,254,254,254”. Select WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New”, and the rule will be added to the mode. After the rule has been set up, all traffic that is not going to the assigned destinations will only be transmitted through WAN1. 52 SSL / IPSec VPN QoS Router 53 SSL / IPSec VPN QoS Router VII. Intranet Configuration This chapter introduces how to configure ports and understand how to configure intranet IP addresses. 7.1 Port Management Through the device, users can easily manage the setup for WAN ports, LAN ports and the DMZ port by choosing the number of ports, speed, priority, duplex and enable/disable the auto-negotiation feature for connection setting of each port. Mirror Port：Users can configure LAN 1 as mirror port by choosing “Enable Port 1 as Mirror Port”. All the traffic from LAN to WAN will be copied to mirror port. mirror port. Administrator can control or filter the traffic through Once this function is enabled, LAN 1 will be shown as Mirror Port in Physical Port Status, Home page. 54 SSL / IPSec VPN QoS Router DisabledPort： This feature allows users turn on/off the Ethernet port. If selected, the Ethernet port will be shut down immediately and no connection can be made. The default value is "on". Priority： This feature allows users to set the high/low priority of the packet delivery for the Ethernet port. If it is set as High, the port has the first priority to deliver the packet. The default value is “Normal”. Speed Status： This feature allows users to select the network hardware connection speed for the Ethernet port. The options are 10Mbps and 100Mbps. Duplex Status： This feature allows users to select the network hardware connection speed working mode for the Ethernet. The options are full duplex and half duplex. Auto Neg.： The Auto-Negotiation mode can enable each port to automatically adjust and gather the connection speed and duplex mode. Therefore, if Enabled Auto-Neg. selected, the ports setup will be done without any manual setting by administrators. VLAN： This feature allows administrators to set the LAN port to be one or more disconnected network sessions. All of them will be able to log on to the Internet through the device. Members in the same network session (within the same VLAN) can see and communicate with each other. Members in different VLAN will not know the existence of other members. 55 SSL / IPSec VPN QoS Router VLAN All： Set VLAN All port to be the public area of VLAN so that it can be connected to other VLAN networks. A server should be constructed for the intranet so that all VLAN group can visit this server. Set one of the network ports as VLAN All. Connect the server to VLAN All so that computers of different VLAN groups can be connected to this server. Moreover, the port where the administrator locates must be set as VLAN All so that it can be connected to the entire network to facilitate network management. 56 SSL / IPSec VPN QoS Router 7.2 Port Status Summary： There are Network Connection Type, Interface, Link Status (Up/Down), Port Activity (Port Enabled), Priority Setting (High or Normal), Speed Status (10Mbps or 100Mbps), Duplex Status (half duplex or full duplex), Auto Neg. (Enabled/Disabled), and VLAN. Statistics： The packet data of this specific port will be displayed. Data include receive/ transmit packet count, 57 SSL / IPSec VPN QoS Router receive/ transmit packet Byte count and error packet count. Users may press the refresh button to update all real-time messages. 58 SSL / IPSec VPN QoS Router 7.3 IP/ DHCP With an embedded DHCP server, it supports automatic IP assignation for LAN computers. (This function is similar to the DHCP service in NT servers.) It benefits users by freeing them from the inconvenience of recording and configuring IP addresses for each PC respectively. When a computer is turned on, it will acquire an IP address from the device automatically. This function is to make management easier. 59 SSL / IPSec VPN QoS Router Dynamic IP： Client lease Time： Check the option to activate the DHCP server automatic IP lease function. If the function is activated, all PCs will be able to acquire IP automatically. Otherwise, users should configure static virtual IP for each PC individually. Range Start： This is to set up a lease time for the IP address which is acquired by a PC. The default is 1440 minutes (a day). Users can change it according to their needs. The time unit is minute. 60 SSL / IPSec VPN QoS Router Range End： This is an initial IP automatically leased by DHCP. It means DHCP will start the lease from this IP. The default initial IP is 192.168.1.100. DNS (Domain Name Service)： This is for checking the DNS from which an IP address has been leased to a PC port. Input the IP address of this server directly. DNS (Required) 1： Input the IP address of the DNS server. DNS (Optional) 2： Input the IP address of the DNS server. WINS： If there is a WIN server in the network, users can input the IP address of that server directly. WINS Server： Input the IP address of WINS. Apply： Click “Apply” to save the network configuration modification. Cancel： Click “Cancel" to leave without making any changes. 61 SSL / IPSec VPN QoS Router 7.4 DHCP Status This is an indication list of the current status and setup record of the DHCP server. The indications are for the administrator’s reference when a network modification is needed. DHCP Server： This is the current DHCP IP. Dynamic IP Used： The amount of dynamic IP leased by DHCP. Static IP Used： The amount of static IP assigned by DHCP. DHCP Available： The amount of IP still available in the DHCP server. Total： The total IP which the DHCP server is configured to lease. Host Name： The name of the current computer. 62 SSL / IPSec VPN QoS Router IP Address： The IP address acquired by the current computer. MAC Address： The actual MAC network location of the current computer. Client Lease Time： The lease time of the IP released by DHCP. Delete： Remove a record of an IP lease. DNS Local Database (Future) Normally, DNS sever will be directed to ISP DNS server or internal self- defined DNS server. Qno router also provides “easy” self- defined DNS services, called “DNS Local Database”, which can map website host domain names and the corresponding IP addresses. Host Domain Name Enter the website host domain name. i.e. www.google.com IP Address Enter the corresponding IP address of the host domain above. Add to Llist Add the items into the list below. 63 SSL / IPSec VPN QoS Router Delete selected item Delete the items chosen. ※ Note! (1) Users MUST enable DCHP server service to enable DNS local database. (2) Users must set DHCP server DNS IP address as the router LAN IP. For example, LAN is 10.10.10.1, as shown in the following figure. Therefore, DCHP DNS IP address must be 10.10.10.1 to make DNS local database in effect. (3) After enabling DNS local database, if there is no host domain names in the list, the router will still use ISP DNS server or internal DNS server for lookup. Test if DNS local database is effective: Assumed tw.yahoo.com IP address is 10.10.10.199, as the following figure. 64 SSL / IPSec VPN QoS Router (1) System Tool => Diagnostic => DNS Name Lookup (2) Enter tw.yahoo.com for lookup. (3) The IP is 10.10.10.199, confirming the corresponding IP in DNS local database. 65 SSL / IPSec VPN QoS Router 7.5 IP & MAC Binding Administrators can apply IP & MAC Binding function to make sure that users can not add extra PCs for Internet access or change private IP addresses. There are two methods for setting up this function： Block MAC address not on the list This method only allows MAC addresses on the list to receive IP addresses from DHCP and have Internet access. When this method is applied, please fill out Static IP with 0.0.0.0, as the figure below： 66 SSL / IPSec VPN QoS Router IP & MAC Binding 67 SSL / IPSec VPN QoS Router Static IP： There are two ways to input static IP: 1. If users want to set up a MAC address to acquire IP from DHCP, but the IP need not be a specific assigned IP, input 0.0.0.0 in the boxes. The boxes cannot be left empty. 2. If users want DHCP to assign a static IP for a PC every single time, users should input the IP address users want to assign to this computer in the boxes. The server or PC which is to be bound will then acquire a static virtual IP whenever it restarts. MAC Address： Input the static real MAC (the address on the network card) for the server or PC which is to be bound. 68 SSL / IPSec VPN QoS Router Name： For distinguishing clients, input the name or address of the client that is to be bound. The maximum acceptable characters are 12. Enabled： Activate this configuration. Add to list： Add the configuration or modification to the list. Delete selected item： Remove the selected binding from the list. Add： Add new binding. Block MAC address on the list with wrong IP address： When this option is activated, MAC addresses which are not included in the list will not be able to connect with the Internet. Show New IP user： This function can reduce administrator’s effort on checking MAC addresses one by one for the binding. Furthermore, it is easy to make mistakes to fill out MAC addresses on the list manually. By checking this list, administrator can see all MAC addresses which have traffic and are not bound yet. Also, if administrators find that one specific bound MAC address is shown on the list, it means that the user changes the private IP address. Name： Input the name or address of the client that is to be bound. The maximum acceptable characters are 12. Enabled： Choose the item to be bound. Apply： Activate the configuration. Select All： Choose all items on the list for binding. Refresh： Refresh the list. Close： Close the list. 69 SSL / IPSec VPN QoS Router 7.6 IP Group Management IP Group function can combine several IP addresses or IP address ranges into several groups. When you manage user internet access privileges by IP address, you can set up every management functions for users who have same internet access privileges in the same IP group in order to decrease the effort of setting rules for each IP address. For example, you can choose to set up QoS or Access Rule by IP grouping. Thus, you will simplify setting rules. IP Grouping consists of Local IP Group and Remote IP Group. Local IP Group refers to LAN IP groups, and remote IP Group refers to WAN IP groups. Local IP Group list will automatically learn IP addresses having packets that pass through firewall. Moreover, if user changes the IP address, the IP in the list will change accordingly well. For IP information which is in group list, it won't update automatically along with IP list of the left side. Administrators need to modify it manually. 70 SSL / IPSec VPN QoS Router User Edit IP The IP list will show the list which learns the IP addresses automatically on the left under side. You can also modify IP addresses manually. Name Input the name of IP address (or range) showed below. IP Address Input IP address (or range). For example, 192.168.1.200 ~ 250. Add to IP List After setting name and IP address, push this button to add the information into the IP list below. If this IP (or range) is already in the list, you can not add it again. Local Group Set You can choose from the IP list on the left side to set up a local IP group. IP Group Choose IP Group that you would like to modify. If you would like to add new groups, please push “Add Group” button. Group Name When you add new groups, please note if the group name is in the column. Delete Group Choose the group that you would like to delete from the pull- down list, and push the “Delete Group” button. System will ask you again if you would like to delete the group. After pushing the confirmation button, the group will be deleted. You can choose several IPs from IP list on the left side, and push this button to button have them added into the group the right side. Delete Delete self- defined IP or IP range. Apply Click “Apply” to save the network configuration modification Cancel Click “Cancel" to leave without making any changes. Remote IP Group Management: Basically, Remote IP Group setups are exactly the same as Local IP Group setups. However, remote IP group does not have automatically learning functions. Instead, you need to define addresses, ranges and groups manually. For example, 220.130.188.1 to 200 (range). 71 SSL / IPSec VPN QoS Router It is the same setting methods. You should set the IP address or the range of remote IP from the left side first, and choose to add IP address information from the left side into the remote group. 72 SSL / IPSec VPN QoS Router 7.7 Port Group Management Service ports can be grouping as IP grouping. It is convenient to set QoS, firewall access rules, and other functions. User edit port Input the name, protocol, and port range for the specific service port. Name Name the Port in order to identify its property. For example, Virus 135. Protocol Choose the port protocol form the pull down list like TCP, UDP or TCP and UDP. Port Range Input the port range. For example, 135 to 135. Add to Port List After setting name, protocol and port range, push this button to add the information into the Port list below. This port can be from some port groups. 73 SSL / IPSec VPN QoS Router Port GroupSet You can choose from the Port list on the left side to set up a Port group. Group Name When you add new groups, please note if the group name is in the column. For example, Virus. Delete Group Choose the group that you would like to delete from the pull- down list, and push the “Delete Group” button. System will ask you again if you would like to delete the group. After pushing the confirmation button, the group will be deleted. You can choose several ports from Port list on the left side, and push this button button to have them added into the group the right side. Delete Delete self- defined port or port range. Apply Click “Apply” to save the network configuration modification Cancel Click “Cancel" to leave without making any changes. 74 SSL / IPSec VPN QoS Router VIII. QoS (Quality of Service) QoS is an abbreviation for Quality of Service. The main function is to restrict bandwidth usage for some services and IP addresses to save bandwidth or provide priority to specific applications or services, and also to enable other users to share bandwidth, as well as to ensure stable and reliable network transmission. To maximize the bandwidth efficiency, network administrators should take account of the practical requirements of a company, a community, a building, or a café, etc., and modify bandwidth management according to the network environment, application processes or services. 75 SSL / IPSec VPN QoS Router 8.1 Bandwidth Management 76 SSL / IPSec VPN QoS Router 8.1.1 The Maximum Bandwidth provided by ISP In the boxes for WAN1 and WAN2 bandwidth, input the upstream and downstream bandwidth which users applied for from bandwidth supplier. The bandwidth QoS will make calculations according to the data users input. In other words, it will guarantee a minimum rate of upstream and downstream for each IP and Service Port based on the total actual bandwidth of WAN1 and WAN2. For example, if the upstream bandwidths of both WAN1 and WAN2 are 512Kbit/Sec, the total upstream bandwidth will be: WAN1 + WAN2 = 1024Kbit/Sec. Therefore, if there are 50 IP addresses in the Intranet, the 77 SSL / IPSec VPN QoS Router minimum guaranteed upstream bandwidth for each IP would be 1024Kbit/50=20Kbit/Sec. Thus, 20Kbit/Sec can be input for “Mini. Rate” Downstream bandwidth can be calculated in the same way. Attention！ The unit of calculation in this example is Kbit. Some software indicates the downstream/upstream speed with the unit KB. 1KB = 8Kbit. 8.1.2 QoS To satisfy the bandwidth requirements of certain users, the device enables users to set up QoS: Rate Control and Priority Control. Users can select only one of the above QoS choices. Rate Control： The network administrator can set up bandwidth or usage limitations for each IP or IP range according to the actual bandwidth. The network administrator can also set bandwidth control for certain Service Ports. A guarantee bandwidth control for external connections can also be configured if there is an internal server. 78 SSL / IPSec VPN QoS Router Interface： Select on which WAN the QoS rule should be executed. It can be a single selection or multiple selections. Service Port： Select what bandwidth control is to be configured in the QoS rule. If the bandwidth for all services of each IP is to be controlled, select “All (TCP&UDP) 1~65535”. If only FTP uploads or downloads need to be controlled, select “FTP Port 21~21”. Refer to the Default Service Port Number List. 79 SSL / IPSec VPN QoS Router IP Address： This is to select which user is to be controlled. If only a single IP is to be restricted, input this IP address, such as “192.168.1.100 to 100”. The rule will control only the IP 192.168.1.100. If an IP range is to be controlled, input the range, such as “192.168.1.100 ~ 150”. The rule will control IP addresses from 192.168.1.100 to 150. If all Intranet users that connect with the device are to be controlled, input “0” in the boxes of IP address. This means all Intranet IP addresses will be restricted. QoS can also control the range of Class B. Direction： Upstream: Means the upload bandwidth for Intranet IP. Downstream: Means the download bandwidth for Intranet IP. Server in LAN, Upstream: If a Server for external connection has been built in the device, this option is to control the bandwidth for the traffic coming from outside to this Server. Server in LAN, Downstream: If there are web sites built in the Intranet, this option is to control the upload bandwidth for the connections from outside to this Server. For example, game servers have been built in many Internet cafés. This rule can be used to control the bandwidth for connections from outside to the game server of a café to update data. In this way, game players inside the café will not be affected. Min. & Max. Rate： The minimum bandwidth: The rule is to guarantee minimum available (Kbit/Sec) bandwidth. The maximum bandwidth: This rule is to restrict maximum available bandwidth. The maximum bandwidth will not exceed the limit set up under this rule. Attention! The unit of calculation used in this rule is Kbit. Some software indicates download/upload speed by the unit KB. 1KB = 8Kbit. 80 SSL / IPSec VPN QoS Router Bandwidth sharing： Sharing total bandwidth with all IP addresses: If this option is selected, all IP addresses or Service Ports will share the bandwidth range (from minimum to maximum bandwidth). Assign bandwidth for each IP address: If this option is selected, every IP or Service Port in this range can have this bandwidth (minimum to maximum). For example, If the rule is set for the IP of each PC, the IP of each PC will have the same bandwidth. Attention: If “Share-Bandwidth” is selected, be aware of the actual usage conditions and avoid an improper configuration that might cause a malfunction of the network when the bandwidth is too small. For example, if users do not want an FTP to occupy too much bandwidth, users can select the “Share-Bandwidth Mode”, so that no matter how much users use FTPs to download information, the total occupied bandwidth is fixed. Enable： Add to list： Move up & Move down： Activate the rule. Add this rule to the list. QoS rules will be executed from the bottom of the list to the top of the list. In other words, the lower down the list, the higher the priority of execution. Users can arrange the sequence according to their priorities. Usually the service ports which need to be restricted, such as BT, e-mule, etc., will be moved to the bottom of the list. The rules for certain IP addresses would then be moved upward. Delete selected Remove the rules selected from the Service List. items： Show Table： Display all the Rate Control Rules users made for the bandwidth. Click “Edit” to modify. Apply： Click “Apply” to save the configuration Cancel： Click “Cancel" to leave without making any change. Show Table： 81 SSL / IPSec VPN QoS Router 8.2 Session control Session management controls the acceptable maximum simultaneous sessions of Intranet PCs. This function is very useful for managing connection quantity when P2P software such as BT, Thunder, or emule is used in the Intranet causing large numbers of sessions. Setting up proper limitations on sessions can effectively control the sessions created by P2P software. It will also have a limiting effect on bandwidth usage. In addition, if any Intranet PC is attacked by a virus like Worm.Blaster and sends a huge number of session requests, session control will restrict that as well. Session Control and Scheduling： Disabled： Disable Session Control function. This option enables the restriction of maximum external sessions to each Single IP cannot Intranet PC. When the number of external sessions reaches the limit, to exceed __ session： allow new sessions to be built, some of the existing sessions must be closed. For example, when BT or P2P is being used to download information and the sessions exceed the limit, the user will be unable to connect with other services until either BT or P2P is closed. 82 SSL / IPSec VPN QoS Router When single IP exceed __： If this function is selected, when the user’s port session reach the limit, this user will not be able to make a new session for five minutes. Even if the previous session has been closed, new sessions cannot be made until the setting time ends. If this function is selected, when the user’s port connections reach the limit, all the lines that this user is connected with will be removed, and the user will not be able to connect with the Internet for five minutes. New connections cannot be made until the delay time ends. Scheduling： If “Always” is selected, the rule will be executed around the clock. If “From…” is selected, the rule will be executed according to the configured time range. For example, if the time control is from Monday to Friday, 8:00am to 6:00pm, users can refer to the following figure to set up the rule. Apply： Click “Apply” to save the configuration. Cancel： Click “Cancel" to leave without making any change. 83 SSL / IPSec VPN QoS Router Exempted Service Port or IP Address Service Port： Choose the service port. Source IP： Input the IP address range or IP group. Enabled： Activate the rule. Add to list： Add this rule to the list. Delete seleted item： Remove the rules selected from the Service List. Apply： Click “Apply” to save the configuration. Cancel： Click “Cancel" to leave without making any change. 84 SSL / IPSec VPN QoS Router 8.3 Hardware Optimization(Future) This flagship router not only provides high processing performance but also launches “hardware optimization’ function for bandwidth control and traffic prioritization. The main purpose is to process the bandwidth functions through hardware design, which can accerlate and prioritize the traffic distribution and usage without wasting CPU and system resources. Hardware optimization will speed up the router processing, carry huge connection sessions and PCs, and provide stable and excellent network environment. Service Optimization: Service ports that online games and video softwares will be the highest priority. games or videos traffic in first priority. Router can process these In this way, users can play games or watch videos fluently without disconnection even when the traffic is full. MAC address Pull down menus includes: (1) Source MAC address: Hardware optimization will only be effective to guarantee the traffic in high priorities when the traffic rules match source MAC addresses. 85 SSL / IPSec VPN QoS Router (2) Destination MAC address: Hardware optimization will only be effective to guarantee the traffic in high priorities when the traffic rules match destination MAC addresses. (3) None: The traffic rules neither match traffic rules nor check MAC addresses. IP address Pull down menus includes: (1) Source IP address: Hardware optimization will only be effective to guarantee the traffic in high priorities when the traffic rules match source IP addresses. (2) Destination IP address: Hardware optimization will only be effective to guarantee the traffic in high priorities when the traffic rules match destination IP addresses. (3) None: The traffic rules neither match traffic rules nor check MAC addresses. IP Protocol Choose service port protocols for games, videos, or other network applications required to be prioritized. You can choose TCP, UDP, or any other protocols listed. Action Input service ports for games, videos, or other network applications required to be prioritized. Range is 1~65535. Enable Activate the rule. Add to list Add this rule to the list. Delete selected Remove the rules selected from the Service List. entry 86 SSL / IPSec VPN QoS Router 8.4 Smart QoS The smart QoS function enables the administrators to constrain the bandwidth occupied automatically without any configuring. Enabled QoS： Choose to apply QoS function. When the usage of any WAN’s bandwidth is Input the required rate value into the column. The over than___%, Enable Smart QoS default is 60%. Each IP’s upstream bandwidth threshold Input the max. upstream rate for intranet IPs. (for all WAN)： Each IP’s downstream bandwidth threshold Input the max. downstream rate for intranet IPs. (for all WAN) ： If any IP’s bandwidth is over maximum When any IP uses more bandwidth than the above threshold, its maximum bandwidth will upstream or downstream settings, the IP will be remain： restricted for the following upstream or downstream bandwidth settings. Enabled Penalty Mechanism： After choosing “Enabled Penalty Mechanism”, the device will enable the penalty conditions internally. When the IP still uses more upstream or downstream bandwidth than the setting, the device will execute the penalty conditions automatically. 87 SSL / IPSec VPN QoS Router Show Penalty IP： The IPs which are under penalty mechanism will be shown on the list. Scheduling： If “Always” is selected, the rule will be executed around the clock. If “From…” is selected, the rule will be executed according to the configured time range. For example, if the time control is from Monday to Friday, 8:00am to 6:00pm, users can refer to the following figure to set up the rule. 88 SSL / IPSec VPN QoS Router IX. Firewall This chapter introduces firewall general policy, access rule, and content filter settings to ensure network security. 9.1 General Policy The firewall is enabled by default. If the firewall is set as disabled, features such as SPI, DoS, and outbound packet responses will be turned off automatically. Meanwhile, the remote management feature will be activated. The network access rules and content filter will be turned off. Firewall： This feature allows users to turn on/off the firewall. SPI (Stateful Packet This enables the packet automatic authentication detection technology. Inspection)： The Firewall operates mainly at the network layer. By executing the dynamic authentication for each connection, it will also perform an alarming function for application procedure. Meanwhile, the packet authentication firewall may decline the connections which use non-standard communication protocol. 89 SSL / IPSec VPN QoS Router DoS (Denial of Service)： This averts DoS attacks such as SYN Flooding, Smurf, LAND, Ping of Death, IP Spoofing and so on. Block WAN request： If set as Enabled, then it will shut down outbound ICMP and abnormal packet responses in connection. If users try to ping the WAN IP from the external, this will not work because the default value is set as activated in order to decline the outbound responses. Remote Management： To enter the device web- based UI by connecting to the remote Internet, this feature must be activated. In the field of remote browser IP, a valid external IP address (WAN IP) for the device should be filled in and the modifiable default control port should be adjusted (the default is set to 80, modifiable). Multicast Pass Through： There are many audio and visual streaming media on the network. Broadcasting may allow the client end to receive this type of packet message format. This feature is off by default. Prevent ARP Virus This feature is designed to prevent the intranet from being attacked by Attack： ARP spoofing, causing the connection failure of the PC. This ARP virus cheat mostly occurs in Internet cafes. When attacked, all the online computers disconnect immediately or some computers fail to go online. Activating this feature may prevent the attack by this type of virus. 90 SSL / IPSec VPN QoS Router Advanced Setting Packet Type: This device provides three types of data packet transmission: TCP-SYN-Flood, UDP-Flood and ICMP-Flood. WAN Threshold: When all packet values from external attack or from single external IP attack reach the maximum amount (the default is 15000 packets/Sec and 2000 packets/Sec respectively), if these conditions above occurs, the IP will be blocked for 5 minutes ( the default is 5 minutes OBJ 176 ). Users can adjust the threshold value and the blocking duration to effectively deal with external attack. The threshold value should be adjusted from high to low. LAN Threshold: When all packet values from internal attack or from single internal IP attack reach the maximum amount (the default is 15000 packets/Sec and 2000 packets/Sec respectively), if these conditions above occurs, the IP will be blocked for 5 minutes (the default is 5 minutes). Users can adjust the threshold value and the blocking duration to effectively deal with external attack. The threshold value should be adjusted from high to low.

SSL VPN For SSL VPN, clients only need a web browser to access to Central servers. After verifying the ID, clients can access to the company’s internal resources, such as Internet services, Microsoft terminal services, remote desktop services, online neighborhood networks, and secure tunnel functions through the portal. Meanwhile, different users or groups can access to different interfaces according to the web administrator’s configurations, which satisfies external and mobile users' security requirements. Below introduces SSL VPN related settings. SSL (Secure Sockets Layer) is a protocol that ensures secure data transmission over the Internet via HTTPS encryption, including server authentication, user authentication, and SSL data link integrity and security. SSL VPN is an LAN application service that remote users are provided with web page security through a SSL VPN gateway. Because SSL VPN uses a standard, built-in web browser SSL/HTTPS secure transmission mechanism, there are no required installations or settings for clients. Clients can access remote data via a web browser such as IE or Netscape. This simple setup requires no client software, costs less and is highly adaptable with other networks. Administrators can also use the same ID for user ID authentication mechanism, network access, and classification management. This prevents enterprise information’s complete transparency and provides an increasing level of security safeguards. 148 SSL / IPSec VPN QoS Router 12.1 Status Status shows current SSL VPN users' online status. Tunnel(s) Used: Display the amount of previously set tunnels. Tunnel(s) Available: Display the amount of unused tunnels. User: Display the current SSL tunnel user name. Group: Display the name of current SSL tunnel using Group. IP: Display current users' SSL tunnel remote IP addresses. Login Time: Display current SSL tunnel users' login time. User Type: Display whether the user is an administrator or a staff. Logout: Logout when clicking on the icon. 12.2 Group Summary Group Summary table displays group setting information. Group settings can be modified here and new users can also be added. Group: Display the group’s name. SSL VPN has 4 built-in groups by default (All Users, Supervisor, Mobile User, & Branch Staff). If one group needs to be edited, click on its name to access the group management page. Domain: Display the authentication server name used corresponding to certain group, which is served as Local Database by default. 149 SSL / IPSec VPN QoS Router User: Click "Detail" to view a specific group's user names and types. Add New Group: Click the "Add New Group" tab, entering the group admin section to add a new group. 12.3 Group Management Group Management helps the web administrator organize users’ access to internal service resources in groups. It can be configured by following 3 steps: Domain Management, User management, and Service Resource management. In addition, SSL VPN's unique "One- Click" makes your basic configurations fast. One Click: SSL VPN provides one-click setting. With fewest configurations, all users can use SSL tunnels to access an open internal resource. While in "All Users" group, the authentication server settings support the current enterprise authentication server. So all users, after being identified via the authentication server, will be directed to the portal and can use the full range of enterprise resources. For Authentication server settings, see step one below: Domain Management. 150 SSL / IPSec VPN QoS Router 151 SSL / IPSec VPN QoS Router Group Name: SSL VPN has build-in 4 groups (All Users, Supervisor, Mobile User, and Branch Staff). “All Users” is enabled by default, while others are be disabled. You can select ” Group Enable” to enable the group setting or click on “ Add New Group” button to add others group names. Add New Group Group Name: Import a group name. Apply: Click "Apply" tab to save recent changed settings; new group names will appear in the drop down menu. Cancel: Click "Cancel" to clear any recent changes to the settings. Each group must follow below steps (Domain Management, User management, and Service resource management) to complete group settings. Step 1: Domain Management Domain Management is used to determine which authentication server will be used to authenticate users at login. The default authentication server type is local database. SSL VPN supports external authentication services and can be combined with an enterprise's current authentication server for a 152 SSL / IPSec VPN QoS Router simplified deployment. If no suitable authentication servers can be chosen from the list, click "Add New Domain" to create a new one. All authentication servers with defined settings will be displayed on Domain Assign: Management list. You are required to choose one authentication server to be assigned to this group. Each group can only be assigned to one type of authentication server. Default is Local Database. If there are changes to the domain servers designated by All Users, other groups that have yet to enable will also be modified accordingly. Domain Names: Display all authentication server names. Authentication Type: Display authentication server type. Authentication Display external authentication server IP addresses. If the Authentication Type is IP: server Local Database, the authentication server IP address will not be displayed. 153 SSL / IPSec VPN QoS Router User Database: For external authentication servers, the user database will be: "Apply User Database” and "Customize User Database". Click "Apply User database", then there is no need to establish additional user data, and the system will directly apply the external authentication server's internal user database settings. As long as the users belong to this authentication server group, they can use the group's resources. Note: If multiple groups designate the same authentication server for users, only one group will be able to use the built-in user database at one time. For this reason, it is recommended that the largest group be designated to use the built-in user database and other smaller groups use the "Customize User Database". Select the "Customize User Database", the administrator must add a new user to the group (See step two: User management). If users have not been set by the administrator, users of the authentication server can still pass the authentication, but they will not be able to access the web portal to use internal enterprise resources. Edit: Click on the "Edit" tab to make changes to the server addresses and authentication domain names. Authentication server type and authentication service name cannot be altered. If you want to change the authentication server type and authentication service name, delete them, and then set up a new authentication server. Delete: Click on the recycle bin icon to delete authentication server settings. Adding New Authentication Service SSL VPN, in addition to Local Database, supports another 7 kinds of authentication server types: 154 SSL / IPSec VPN QoS Router Radius-PAP/CHAP/MSCHAP/MSCHSPV2, NT-Domain, Active Directory, and LDAP. 1.

Submit: Click on the "Submit" tab to save changes Cancel: Click "Cancel" to clear any recent changes to the settings. If you want to use the one-click function, after you have added new authentication servers, complete the setup by assigning the All Users group authentication server to the newly created authentication server. Note: All of the users in this authentication server can link to the web portal and access all of the enterprise resources pre-determined by administrators. Administrators do not need to define settings for step 2 (User management) and step 3 (Service resources management). 159 SSL / IPSec VPN QoS Router Inactivity Timeout This option is activated on all users, no matter in which group. System can log off idle users to release connection, bandwidth and system resource. You can fill the idle time in minutes to the field. ※Attention There is also idle time settings in User Management as below figure： 160 SSL / IPSec VPN QoS Router Therefore, single users will have different idle logout time, which is dominated by single user setting; otherwise users will log out in accordance with group setting of idle time. Step 2: User Management User Management determines who belongs to this group and have the rights to use specific resources. Newly added users will appear on the user list; click on "Assign to this Group" column to designate a user to this group. If "Domain Management" is set to "Customize User Database" and when the user list does not have a suitable user, click "Add New User" to create a new one. 161 SSL / IPSec VPN QoS Router Assign to this Select a user from the user list to assign to this group. One user can be Group: assigned to one group only. User Name: Display customized user name. Please note: The built- in users of the authentication server database in Domain Management will not display on the user list. Edit: User passwords (if Local Database), expiration dates, user classifications, and inactive timeouts can be edited or modified, but user authentication servers and user names cannot. If you want to modify a user name, first delete it, and then add a new modified user name. Delete: Delete this user. Add New User Click on “Add new user” and the window will pop up as below. Please note: In addition to Local Database, user names and passwords must correspond to the selected authentication server’s user names. 162 SSL / IPSec VPN QoS Router Domain Name: Display the authentication server name used by this group. User Name: Enter authentication server’s user name. Password: For Local Database, enter user passwords. Passwords do not need to be entered if Local Database is not used. Expiration Date (yyyy/mm/dd): Enter users' permitted time limit. For example, if the expiration date is set to November 1, 2007, then the user will be denied beginning on November 2, 2007 at 12: 00 AM. User Type: If set to "Administrator", the user will login on the router management UI. If set to "U user", the user will login on the web portal. Please note: Only Local Database users can be set as "Administrator"; external authentication server users can only be "Users" and cannot login on the router management UI. 163 SSL / IPSec VPN QoS Router Inactive timeout: Even though a user has logged in via the web portal, he/she will be forced to logout (timeout) due to inactivity after 10 minutes. If a user logs into the web portal to access enterprise resources using a SSL in an unsafe environment, a shorter timeout time is recommended to mitigate risk if the user is logged in but inactive. Add to List: After completing the above settings, click on "add to list" to add newly created user settings to the corresponding list. Save Setting: After complete settings, click on the “Save Setting” tab to save. Cancel: Click on the “Cancel” tab to cancel all unsaved settings. Exit: Click on the “Exit” tab to close the “add new user” window. Step 3: Service Resource Management: (1) Allow the SSL users to access the same subnet, but not to transfer the traffic to the router completely： This is factory default; users can access some specific services within servers that are in the same subnet (the subnet which virtual passage was destined). The traffic which is irrelevant to intranet (for example, to visit the News web page) will be forwarded to local gateway router. (2) The SSL users can choose transferring the traffic to the router completely： To indicate the users can choose all the traffic to be directed to Qno Firewall Router, after Qno Firewall router allows users to connect Virtual Passage successfully. Therefore, users can access not only the servers or services within the same subnet in intranet, but also can access to internet through non-split tunnel of the Firewall Router WAN IP, if the Firewall Router dosen’t control the connecting for Virtual Passage. As the figure below, remote users can decide if all traffic is forwarded to Qno Firewall/Router by selecting the「Connecting Using Virtual Passage」 check box in the Virtual Passage control page. Otherwise, the traffic which is not about the intranet will be forwarded to local gateway 164 SSL / IPSec VPN QoS Router router. (3) Force the traffic of SSL users to transfer to the router completely： To incicate the traffic of each user connecting the Virtual Passage successful will be forwarded to central SSL VPN server of Qno Firewall Router and can not cancel “使用遠端 SSL 網路的預設 閘道” selection as figure below. 165 SSL / IPSec VPN QoS Router 12.4 Domain Management In addition to selecting 12.3 “Group Management”, SSL VPN can also provide authentication to display Domain Management. All authentication services will be shown in the Domain Management list. Groups using authentication services will be displayed according to the authentication server name. All User Group Step One: Supervisor Mobile Group Group User Branch Staff Group Domain Management Step 2: User Management Step 3: Service Resource Management: Domain Name: All newly added authentication services will be displayed on the Domain Management list. Authentication Type: Authentication service types are displayed by authentication server name, including: Local Database, Radius- PAP/ CHAP/ MSCHAP/ MSCHAPV2, NT-Domain, Active Directory and LDAP.

For login to the web portal, click “Link to Portal”. 12.8 Advanced Settings Advanced Settings can modify SSL connection ports & add SSL upgrades. 170 SSL / IPSec VPN QoS Router 12.8.1 Virtual Passage A virtual passage is a type of point-to-point SSL client connection. When remote users use a secure tunnel to connect, SSL VPN will establish a virtual web interface. For this reason, you will need to set SSL VPN's secure tunnel client address range so it does not conflict with your company's Internet DHCP IP. Default for 5 SSL users is 192.168.1.200 to 192.168.1.205. Unified IP Management: 171 SSL / IPSec VPN QoS Router The Unified IP Management configuration window can set LAN IP range, DHCP IP range, SSL virtual passage IP range, and PPTP IP address range. LAN Settings: The system default for LAN IP is 192.168.1.1, and subnet mask is 255.255.255.0. Changes can be made based on actual network architecture. Multiple-Subnet Settings: Select "Multiple Subnet", and enter the subnet IP address/ subnet mask you want to add. This function is to add the router's different LAN IPs in different ranges to the router identified LAN. Therefore, PCs in LAN already having configured IPs, which are different from LAN IP range, can still go online directly. For example, there are several IP ranges in LAN, such as 192.168.3.0, 192.168.20.0, 192.168.150.0, etc. When all of these ranges are added to a subnet, the PCs in these ranges don't need to make any modification and can go online. This can be done with your actual internet architecture. Dynamic IP: SSL VPN firewall has 4 Class C DHCP servers and is enabled by default, which can provide PCs in LAN 172 SSL / IPSec VPN QoS Router to get IPs automatically (like DHCP service in NT server). So each PC isn't required to record or set other IP addresses. After a computer starting, SSL VPN firewall will automatically acquire an IP address. Range Start: The initial IP for the 4 ranges by default are 192.168.1.100, 192.168.2.100, 192.168.3.100, and 192.168.3.100. Changes can be made by actual requirements. Range End: The last IP for the 4 ranges by default are 192.168.1.149, 192.168.2.149, 192.168.3.149, 192.168.4.149. Factory default allows to 50 IP addresses in each range. A total of 200 computers can automatically acquire IP addresses. Changes can be made by actual requirements. Virtual Passage: When the client uses SSL secure tunnel to connect to SSL VPN, SSL VPN will assign a LAN IP address to the user. You can use SSL VPN's supported SSL tunnels to adjust "client start addresses" and "client end addresses" to provide ample LAN IP the SSL secure tunnel clients. Ensure that the secure tunnel IP range doesn’t conflict with the DHCP IP range or the PPTP secure tunnel IP range. PPTP IP Address Distribution Range: When a client uses PPTP to dial into the SSL VPN, SSL VPN will assign a LAN IP address for the client. You can adjust “Range Start” and “Range End” by purchasing SSL tunnel quantity. In this way, you can provide sufficient LAN IPs for SSL tunnel users. Please Note: IP ranges for virtual passage cannot have conflict with those in DHCP and PPTP tunnels. 12.8.2 Advanced Configurations The SSL default port is 443. If port 443 is being used by another internal application, you can use the SSL VPN’s service port drop down menu to select a different one (10443, 20443). Remind: If you change a port other than the default 443, when a client connects to the SSL VPN, the port number will have to be entered after the address. 173 SSL / IPSec VPN QoS Router 12.8.3 Password Protection For enhance the robust security connection of SSL, you can avoid illegal users or brute-force-attack by selecting below options. (1) Enable restrict crack calculator administrators can set the number of error times for the single account login, when this account login times are over the number administrators set, system will block this account for a period of time. To enter “Apply”, it will take effect when users login next time. ※If user login with a error password continuously, a warning message will pop up as below figure： ※When the error times over the threshold, system will block this account automatically for few minutes, along with pop up a warning message to remind the users as below figure： 174 SSL / IPSec VPN QoS Router (2) Enable graphics verification When select “Enable graphics verification” and enter “Apply”, the login web page will display graphics verification as below figure when users login next time. Users not only key in the user name/password but also need to key in the correct graphics verification to login SSL connecting successful. 12.8.4 SSL Upgrade Serial Number 175 SSL / IPSec VPN QoS Router In addition to SSL VPN default SSL tunnel, if you want to upgrade for additional tunnels, please contact your Qno distribution representatives to order the upgraded edition. After purchasing, an SSL upgrade serial number will be provided. Enter the serial number in the "SSL Upgrade Serial Number" blank and the tunnel quantity in "SSL Upgrade Tunnel Number". After that, click "Apply", and you can successfully upgrade the SSL tunnels. You can go to “Status” to view “Tunnel(s) Used” and “Tunnel(s) Available” to confirm whether your upgrade is successful or not . SSL Cerificate Import / Export In short, SSL Certificate is an authentication between web browser and host. A comprehensive Certificate includes corporation name, web site name, users account, digital key and validity date of certificate. Web browser will request the web site to show digital certificate when the web browser requests to use SSL mode (https://). If web browser decides to accept the digital certificate, all data between the web site and browser will use certificate digital-key encryption to avoid hacker to access the data. SSL certificate includes public-key and private-key. Public-key is used to encrypt data while the private-key is used to decrypt. When the web browser connects to SSL network (http://), SSL protocol will verifies server and client identities and creates a encryption method with public key. Then, the SSL will start a security process to protect the privacy and data integrity. Generally, if users do not import a legal authentication/authorization SSL certificate verified through third party, web page will display as below figure to warm that users have not getting SSL certificate by legal authorized third party agent. 176 SSL / IPSec VPN QoS Router 177 SSL / IPSec VPN QoS Router The browser older than IE8.0 may display as below figure. 178 SSL / IPSec VPN QoS Router Please note that these warning messages won't influence the operation and usage of the SSL VPN. But if you want to apply a integrity SSL certificate from a third party organization, you need contact these third party organizations(for example: VeriSign) and follow their procedures to apply a integrity SSL certificate for your business. 179 SSL / IPSec VPN QoS Router [SSL certificate inport]: Generally, SSL certificate format looks like the diagram below, and it indicates a .PEM file format which is available in the Qno System. Users only need to copy all the letters (including the “Begin” and “End”) into the notepad file and save to .PEM file. Then, users can import this .PEM file into Qno System. If the SSL certificate is .CER file, users can translate file to .PEM file format by Windows build-in translation tool. Please access to Qno web site to search the related documentation of technology instructions or contact Qno technical department if you do not know how to translate the file. [To export SSL certificate of administrator]： Administrators can not only export the completed SSL certificate from a SSL VPN Firewall Router, but also import the certificate to others SSL VPN Firewall Router. The file format is .PEM file. [To export SSL certificate of User]： Users can export the SSL certificate from PC (excluding private-key) and import to other PCs. The exported file format is .PEM file. 180 SSL / IPSec VPN QoS Router XII. Advanced Function 13.1 DMZ Host/ Port Range Forwarding 13.1.1 DMZ Host When the NAT mode is activated, sometimes users may need to use applications that do not support virtual IP addresses such as network games. We recommend that users map the device actual WAN IP addresses directly to the Intranet virtual IP addresses, as follows: If the “DMZ Host” function is selected, to cancel this function, users must input "0” in the following “DMZ Private IP”. This function will then be closed. After the changes are completed, click “Apply” to save the network configuration modification, or click “Cancel" to leave without making any changes. 13.1.2 Port Range Forwarding Setting up a Port Forwarding Virtual Host: If the server function (which means the server for an external service such as WWW, FTP, Mail, etc) is contained in the network, we recommend that users 181 SSL / IPSec VPN QoS Router use the firewall function to set up the host as a virtual host, and then convert the actual IP addresses (the Internet IP addresses) with Port 80 (the service port of WWW is Port 80) to access the internal server directly. In the configuration page, if a web server address such as 192.168.1.50 and the Port 80 has been set up in the configuration, this web page will be accessible from the Internet by keying in the device actual IP address such as, http://211.243.220.43. At this moment, the device actual IP will be converted into “192.168.1.50” by Port 80 to access the web page. In the same way, to set up other services, please input the server TCP or UDP port number and the virtual host IP addresses. Service： To select from this option the default list of service ports of the virtual host that users want to activate. Such as: All (TCP&UDP) 0~65535, 80 (80~80) for WWW, and 21~21 for FTP. Please refer to the list of default service ports. IP Address： Input the virtual host IP address. Enabled： Activate this function. Service Port Add or remove service ports from the list of service ports. Management： Add to list： Add to the active service content. 182 SSL / IPSec VPN QoS Router Service Port Management The services in the list mentioned above are frequently used services. If the service users want to activate is not in the list, we recommend that users use “Service Port Management” to add or remove ports, as follows： Service Name： Input the name of the service port users want to activate on the list, such as E-donkey, etc. Protocol： To select whether a service port is TCP or UDP. Port Range： To activate this function, input the range of the service port locations users want to activate such as 500~500 or 2300~2310, etc. Add to list： Add the service to the service list.

Show Table: This is a list which displays the current active UPnP functions. Apply: Click “Apply” to save the network configuration modification. Cancel: Click “Cancel" to leave without making any change. 185 SSL / IPSec VPN QoS Router 13.3 Routing In this chapter we introduce the Dynamic Routing Information Protocol and Static Routing Information Protocol. 13.3.1 Dynamic Routing The abbreviation of Routing Information Protocol is RIP. There are two kinds of RIP in the IP environment – RIP I and RIP II. Since there is usually only one router in a network, ordinarily just Static Routing will be used. RIP is used when there is more than one router in a network, and if an administrator doesn’t want to assign a path list one by one to all of the routers, RIP can help 186 refresh the paths. SSL / IPSec VPN QoS Router RIP is a very simple routing protocol, in which Distance Vector is used. Distance Vector determines transmission distance in accordance with the number of routers, rather than based on actual session speed. Therefore, sometimes it will select a path through the least number of routers, rather than through the fastest routers. Working Mode： Select the working mode of the device: NAT mode or router mode. RIP： Click “Enabled” to open the RIP function. Receive RIP versions： Use Up/Down button to select one of “None, RIPv1, RIPv2, Both RIPv1 and v2” as the “TX” function for transmitting dynamic RIP. Transmit RIP versions： Use Up/Down button to select one of “None, RIPv1, RIPv2-Broadcast, RIPv2-Multicast” as the “RX” function for receiving dynamic RIP. 13.3.2 Static Routing When there are more than one router and IP subnets, the routing mode for the device should be configured as static routing. Static routing enables different network nodes to seek necessary paths automatically. It also enables different network nodes to access each other. Click the button “Show Routing Table” (as in the figure) to display the current routing list. 187 SSL / IPSec VPN QoS Router Dest. IP： Input the remote network IP locations and subnet that is to be Subnet Mask： routed. For example, the IP/subnet is 192.168.2.0/255.255.255.0. Gateway： The default gateway location of the network node which is to be routed. Hop Count： This is the router layer count for the IP. If there are two routers under the device, users should input “2” for the router layer; the default is “1”. (Max. is 15.) Interface： This is to select “WAN port” or “LAN port” for network connection location. Add to List： Add the routing rule into the list. Delete Selected Item： Remove the selected routing rule from the list. Show Table： Show current routing table. Apply： Click “Apply” to save the network configuration modification Cancel： Click “Cancel" to leave without making any changes. 188 SSL / IPSec VPN QoS Router 13.4 One to One NAT As both the device and ATU-R need only one actual IP, if ISP issued more than one actual IP (such as eight ADSL static IP addresses or more), users can map the remaining real IP addresses to the intranet PC virtual IP addresses. These PCs use private IP addresses in the Intranet, but after having One to One NAT mapping, these PCs will have their own public IP addresses. For example, if there are more than 2 web servers requiring public IP addresses, administrators can map several public IP addresses directly to internal private IP addresses. Example：Users have five available IP addresses - 210.11.1.1~5, one of which, 210.11.1.1, has been configured as a real IP for WAN, and is used in NAT. Users can respectively configure the other four real IP addresses for Multi-DMZ, as follows: 210.11.1.2 192.168.1.3 210.11.1.3 192.168.1.4 210.11.1.4 192.168.1.5 210.11.1.5 192.168.1.6 Attention！ The device WAN IP address can not be contained in the One-to-One NAT IP configuration. 189 SSL / IPSec VPN QoS Router Enabled One to One NAT： To activate or close the One-to-One NAT function. (Check to activate the function). Private IP Range Begin： Input the Private IP address for the Intranet One-to-One NAT function. Public IP Range Begin： Input the Public IP address for the Internet One-to-One NAT function. Range Length： The numbers of final IP addresses of actual Internet IP addresses. (Please do not include IP addresses in use by WANs.) Add to List： Add this configuration to the One-to-One NAT list. Delete Seleted Item： Remove a selected One-to-One NAT list. Apply： Click “Apply” to save the network configuration modification. Cancel： Click “Cancel" to leave without making any changes. Attention！ One-to-One NAT mode will change the firewall working mode. If this function has been set up, the Internet IP server or PC which is mapped with a LAN port will be exposed on the Internet. To prevent Internet users from actively connecting with the One-on-One NAT server or PC, please set up a proper 190 SSL / IPSec VPN QoS Router denial rule for access, as described Firewall. 13.5 DDNS- Dynamic Domain Name Service DDNS supports the dynamic web address transfer for QnoDDNS.org.cn、3322.org、DynDNS.org and DtDNS.com. This is for VPN connections to a website that is built with dynamic IP addresses, and for dynamic IP remote control. For example, the actual IP address of an ADSL PPPoE time-based system or the actual IP of a cable modem will be changed from time to time. To overcome this problem for users who want to build services such as a website, it offers the function of dynamic web address transfer. This service can be applied from www.qno.cn/ddns, www.3322.org, www.dyndns.org, or www.dtdns.com, and these are free. Also, in order to solve the issue that DDNS server is not stable, the device can update the dynamic IP address with different services at the same time. Select the WAN port to which the configuration is to be edited, for example, WAN 1. Click the hyperlink to enter and edit the settings. 191 SSL / IPSec VPN QoS Router Interface This is an indication of the WAN port the user has selected. DDNS Check either of the boxes before DynDNS.org, 3322.org, DtDNS.com and QnoDDNS.org.cn to select one of the four DDNS website address transfer functions. Username The name which is set up for DDNS. Input a complete website address such as abc.qnoddns.org.cn as a user name for QnoDDNS. Password Dynamic Domain Name The password which is set up for DDNS.

Apply After the changes are completed, click “Apply” to save the network configuration modification. Cancel Click “Cancel" to leave without making any changes. 193 SSL / IPSec VPN QoS Router 13.6 MAC Clone Some ISP will request for a fixed MAC address (network card physical address) for distributing IP address, which is mostly suitable for cable mode users. Users can input the network card physical address (MAC address: 00-xx-xx-xx-xx-xx) here. The device will adopt this MAC address when requesting IP address from ISP. Select the WAN port to which the configuration is to be edited; click the hyperlink to enter and edit its configuration. Users can input the MAC address manually. Press “Apply” to save the setting, and press “Cancel” to remove the setting. Default MAC address is the WAN MAC address. 194 SSL / IPSec VPN QoS Router 13.7 Inbound Load Balance Qno Firewall/Router not only supports efficient Outbound Load Balance, but Inbound Load Balance. It distributes inbound traffic equally to every WAN port to make best use of bandwidth. It also can prevent traffic from unequally distribution and congested. Users can use only one device to satisfy the demand of Inbound/Outbound Load Balance simultaneously. Following introduces how to enable and setup Inbound Load Balance step by step. Attention! In For some models of Qno routers, user can try the function for a period but with time limit. If the function can match your network demand, you can apply for the official version License Key in Qno Official Website (www.qno.com.tw). After applying, auditing, paying and inputting License Key successfully, users can use the official version without time limit. 1. System Tool => License Key => Try to enable “Inbound Load Balance.” After enabling Trial version, “Status and Information” column will display the remaining trial time. If trial expires, the function can not work out at all unless users enter an official License Key. 2. Go to “Inbound Load Balance” in “Advanced Function” and click “Edit” to configure. 3. Enable “Inbound Load Balance.” 195 SSL / IPSec VPN QoS Router 196 SSL / IPSec VPN QoS Router 4. Configure Domain Name and Host IP. Assign DNS service provider and Host IP address. Take the setting on TWNIC as an example, the network structure and IP are as following: WAN1：ADSL ISP A 210.10.1.1 WAN2：ADSL ISP B 200.1.1.1 Domain Name：abc.com.tw Name Server(NS)：ns1.abc.com.tw /ns2.abc.com.tw Go to website of your DNS service provider to modify your own DNS Host/IP, as the following figure: Choose DNS mode, and then fill in the Host name and corresponding IP address of WAN1 and WAN2. Press “Finish” button, the setting will be effective in 24 hours. Attention! Please follow your ISP to modify Host/IP assignment if your upper level isn’t TWNIC! If your DNS agent is other ISP, please refer to the Web configuration provided by your ISP!? 5. Configure Firewall/Router Domain Name 197 SSL / IPSec VPN QoS Router Domain Name: Input the Domain Name which is applied before. The domain name will be shown in following configuration automatically without entering again. Time To Live: Time To Live (the abbreviation is TTL) is time interval of DNS inquiring (second, 0~65535). Too long interval will affect refresh time. Shorter time will increase system’s loading, but the effect of Inbound Load Balance will be more correct. You can adjust according your reality application. Administrator: Enter administrator’s E-mail address, e.g. [email protected]. 6. DNS Server Settings: Add or Modify NS Record. (NS Record) NS Record is the record of DNS server to assign which DNS server translates the domain name. DNS Server Input registered NS Record, ex. ns1, ns2. Interface: Assign WAN IP address as corresponding IP of NS Record. The system will show all acquired enabled WAN IP addresses automatically so that users can check directly. But users have to check if the IP addresses are the same as the corresponding settings on 198 SSL / IPSec VPN QoS Router TWNIC DNS service provider. (Ex. ns1.abc.com.tw WAN1: 210.10.1.1, ns2.abc.com.twWAN2: 200.1.1.1) 7. Host Record: Add or modify host record. (A Record) Input the host name which provides services. E.g. mail server or FTP. Host Name: WAN IP: Check corresponding A Record IP (WAN Port IP). If more than one IPs is checked, Inbound traffic will be distributed on this WANs. 8. Alias Record : Add or modify alias record (CNAME Record) This kind of record allows you to assign several names to one computer host, which may provide several services on it. For instance, there is a computer whose name is “host.mydomain.com” (A record). It provides WWW and Mail services concurrently. Administrator can configure as two CNAME: WWW and Mail. They are “www.mydomain.com” and “mail.mydomain.com”. They are both orientated to “host.mydomain.com.” You can also assign several domain names to the same IP address. One of the domains will be A record corresponding server IP, and the others will be alias of A record domain. If 199 SSL / IPSec VPN QoS Router you change your server IP, you don’t have to modify every domain one by one. Just changing A record domain, and the other domains will be assigned to new IP address automatically. Alias: Input Alias Record corresponding to A Record. Target: Input the existed A Record domain name. 9. Mail Server: Add or modify mail server record. MX Record is directed to a mail server. It orientates to a mail server according to the domain name of an E-mail address. For example, someone on internet sends a mail to [email protected]. The mail server will search MX Record of mydomain.com through DNS. If the MX Record exists, sender PC will send mails to the mail server assigned by MX Record. Host Display the host name without domain name of mail host. Name: Weight: Indicate the order of several mail hosts, the smaller has more priority. Mail Input the server name which is saved in A Record or external mail server. Server: Click “Apply” button to save the configuration. Besides, users have to configure DNS 200 SSL / IPSec VPN QoS Router service port as following description. 10. Enable DNS Query (DNS service port) in Access Rule of Firewall setting.

Two similar devices are used to be the backup for each other. One of these devices is employed for major network transmitting, and the other redundant device will take over when the master device fails to assure that network transmitting and services never break down. Therefore, administrators will have more opportunity and time to deal with the master device problems. Besides general HA, Qno also provides advanced HA function that enables two devices to operate simultaneously. It brings full cost efficiency without making another device idle. It does not have to be the same model. All of Qno devices which support HA can achieve the function. High Availability Enable: Activate HA function. Disable: Disable HA function. Mode (1) Hardware Backup Mode It is the general backup mode. The master device takes responsibility of network transmitting and the other one is set as idle. When the master device fails transmitting, it will send out the message to the idle device for taking over network transmitting immediately. (2) Two devices are operating simultaneously Two devices operate outbound linking simultaneously, but they are still separated as 211 SSL / IPSec VPN QoS Router Master device and Backup device. In normal situation, Master device is major DHCP IP issuer, and Backup device will disable DHCP issuing automatically. When Master device fails transmitting, the Backup device will take over all outbound links and enable DHCP server to provide IP addresses. Following is the description of the two different modes. Hardware Backup ※ Operation-Master Mode Status Status of the backup device Indicates the master device will operate for all outbound links. When the master device fails transmitting, the backup device will take over. “Status- Normal” indicates the device operates well. Indicates status of backup device. If the status is normal, administrators can login the device remotely to manage. (Remote Management should be enabled). “Status- Abnormal” indicates the backup device can not be detected or does exist, and need to inspect the backup device actual status. 212 SSL / IPSec VPN QoS Router Operation-Backup Mode Indicates the backup device will take over when the master fails transmitting. WAN and LAN IP setting in backup device should be the same as those of master device. The backup device should not be in charge of network transmitting and DHCP server. ※ If the original LAN IP addresses are issued by Master device, DHCP server setting of Backup device should be the same as Master device. The Backup device can keep DHCP functioning and there will be no LAN disconnection. LAN IP of the backup device Input LAN IP of Master mode, which is backed up. MAC Address of the backup Input Master device MAC address, which is backed up. device: Status “Status- Normal” indicates the status is idle. Master device operates normally. “Status- Backup” indicates the device takes over all the network transmitting. The status will return to “Normal” when Master device boots normally and send a message to the backup device. Then, the status will return to Normal, which the backup device remains idle. Two devices are operating simultaneously: Operation-Master Mode Besides operating network with another device, Master device is also 213 SSL / IPSec VPN QoS Router the DHCP server to issue LAN IP addresses. Although Slave device also supports outbound linking, its DHCP server is disabled. WAN Backup (The Checked WANs are not The checked WANs will works in the other device. For an example, if WAN1 works in this device, and WAN2 works in the other device, working in this device.) WAN2 should be checked. LAN Gateway Backup Input LAN IP of Slave device. The IP should be different from LAN IP of Master device. MAC Address of the backup device Input LAN MAC of Slave device. It should be different from LAN MAC of Master device. Status “Status-Normal” means both two devices operate normally. “Status-Backup” indicates Slave mode has problems, and the device enables backup to take over WAN Operation-Slave Mode Although working with master device, Backup device’s DHCP server is disabled. LAN users need to transmit traffic through the WAN on Slave device. You should add LAN IP of Slave device into Master device DHCP server default gateway, which is DHCP server IP address. For example, if the DHCP server’s IP of Master device is 192.168.1.1, and the subnet mask is 255.255.255.0, Salve device should be in the same subnet, ex. 192.168.1.2. WAN Backup The checked WANs will works in another device. For an example, if 214 SSL / IPSec VPN QoS Router (The Checked WANs are not WAN1 works in this device, and WAN2 works in another, WAN2 working in this device.) should be checked. LAN Gateway Backup Input the LAN IP of Master device. It should be different from Slave device’s IP. (Must be in the same subnet.) MAC Address of the backup device Input the LAN MAC of Master device. It should be different from Salve device’s LAN MAC. Status “Status-Normal” indicates both devices work normally; “Status-Backup” indicates the Backup device is enabled for backing up Master device to take over WAN connection and DHCP issuing function. 215 SSL / IPSec VPN QoS Router 14.7 License Key Users have to purchase License Key to “enable” some functions in Qno Firwalls/Routers series or upgrade to “Official Version”(not trial version), such as QnoSniff or Inbound Load Balance, etc. Current Time: Before inputing License Key, the device will check whether current time is correct and whether License Key is still in valid period.

The following guides users to block this virus' corresponding port for prevention. a. Add this TCP135-139, UDP135-139 and TCP445 Port. b. Use the "Access Rule" in the firewall and set to block these three ports. 25 SSL / IPSec VPN QoS Router Use the same method to add UDP [UDP135~139] and TCP [445~445] Ports. c. Enhance the priority level of these three to the highest. 26 SSL / IPSec VPN QoS Router （3）Block QQLive Video Broadcast Setting QQLive Video broadcast software is a stream media broadcast software. Many clients are bothered by the same problem: When several users apply QQLive Video broadcast software, a greater share of the bandwidth is occupied, thus overloading the device. Therefore, the device responds more slowly or is paralyzed. If the login onto the QQLive Server is blocked, the issue can be resolved. The following relates to Qno products and provides users with solutions by introducing users how to set up the device. a). Log into the device web- based UI, and enter “Firewall -> Access Rule’. b). Click "Add New Rule" under "Access Rule" page. Select "Deny" in "Action" under the "Service” rule setting, followed by the selection of "All Traffic [TCP&UDP/1~65535]" from "the service" and select "Any" for Interface, "Any" for source IP address (users with relevant needs may select either "Single" or "Range" to block any QQLive login by using one single IP or IP range), followed by the selection of "Single" of the "Dest. IP and enter the IP address as 121.14.75.155" for the QQLive Server (note that there are more than one IP address for QQLive server. Repeated addition may be needed). Lastly, select "Always" under the Scheduling setting so that the QQLive Login Time can be set. (If necessary, specific time setting may be undertaken).

Click "Apply" to block QQLive video broadcast. 28 SSL / IPSec VPN QoS Router （4）ARP Virus Attack Prevention 1. ARP Issue and Information Recently, many cyber cafes in China experienced disconnection (partially or totally) for a short period of time, but connection is resumed quickly. This is caused by the clash with MAC address. When virus-contained MAC mirrors to such NAT equipments as host devices, there is complete disconnection within the network. If it mirrors to other devices of the network, only devices of this affected network have problems. This happens mostly to legendary games especially those with private servers. Evidently, the network is attacked by ARP, which aims to crack the encryption method. By doing so, they hackers may intercept the packet data and user information through the analysis of the game's communication protocol. Through the spread of this virus, the detailed information of the game players within the local network can be obtained. Their account and information are stolen. The following describes how to prevent such virus attack. First, let us get down to the definition of ARP (Address Resolution Protocol). In LAN, what is actually transmitted is "frame", in which there is MAC address of the destination host device. So-called “Address Analysis” refers to the transferring process of the target IP address into the target MAC address before the host sends out the frame. The basic function of ARP protocol aims to inquire the MAC address of the target equipment via the IP address of the target equipment so as to facilitate the communications. The Working Principle of ARP Protocol: Computers with TCP/IP protocol have an ARP cache, in which the IP address corresponds to the MAC address (as illustrated). IP Address MAC 192.168.1.1 00-0f-3d-83-74-28 192.168.1.2 00-aa-00-62-c5-03 192.168.1.3 03-aa-01-75-c3-06 …… …… For example, host A (192.168.1.5) transmits data to Host B (192.168.1.1) .Transmitting data, Host A searches for the destination IP address from the ARP Cache. If it is located, MAC address is known. Simply fill in the MAC address for transmission. If no corresponding IP address is found in ARP cache, Host A will send a broadcast. The MAC address is “FF.FF.FF.FF.FF.FF,” which is to inquire all the host devices in the same network session about “What is the MAC address of “192.168.1.1"? Other host devices do not respond to the 29 SSL / IPSec VPN QoS Router ARP inquiry except host device B, which responds to host device A when receiving this frame: “The MAC address of 192.168.1.1 is 00-aa-00-62-c6-09”. So Host A knows the MAC address of Host B, and it can send data to Host B. Meanwhile, it will update its ARP cache. Moreover, ARP virus attack can be briefly described as an internal attack to the PC, which causes trouble to the ARP table of the PC. In LAN, IP address was transferred into the second physical address (MAC address) through ARP protocol. ARP protocol is critical to network security. ARP cheating is caused by fake IP addresses and MAC addresses, and the massive ARP communications traffic will block the network. The MAC address from the fake source sends ARP response, attacking the high-speed cache mechanism of ARP. This usually happens to the cyber cafe users. Some or all devices in the shop experience temporal disconnection or failure of going online. It can be resolved by restarting the device; however, the problem repeats shortly after. Cafe Administrators can use arp –a command to check the ARP table. If the device IP and MAC are changed, it is the typical symptom of ARP virus attack. Such virus program as PWSteal. lemir or its transformation is worm virus of the Trojan programs affecting Windows 95/ 98/ Me/ NT/ 2000/ XP/ 2003. There are two attack methods affecting the network connection speed: cheat on the ARP table in the device or LAN PC. The former intercepts the gateway data and send ceaselessly a series of wrong MAC messages to the device, which sends out wrong MAC address. The PC thus cannot receive the messages. The later is ARP attack by fake gateways. A fake gateway is established. The PC which is cheated sends data to this gateway and doesn't go online through the normal device. From the PC end, the situation is "disconnection“. For these two situations, the device and client setup must be done to prevent ARP virus attack, which is to guarantee the complete resolution of the issue. The device selection is advised to take into consideration the one with anti-ARP virus attack. Qno products come squarely with such a feature, which is very user-friendly compared to other products. 2. ARP Diagnostic If one or more computers are affected by the ARP virus, we must learn how to diagnose and take appropriate measures. The following is experience shared by Qno technical engineers with regard to the ARP prevention. Through the ARP working principle, it is known that if the ARP cache is changed and the device is constantly notified with the series of error IP or if there is cheat by fake gateway, then the issue of disconnection will affect a great number of devices. This is the typical ARP attack. It is very easy to judge if there is ARP attack. Once users find the PC point where there is problem, users may enter the DOS system to 30 SSL / IPSec VPN QoS Router conduct operation, pining the LAN IP to see the packet loss. Enter the ping 192.168.1.1 (Gateway IP address) as illustrated. If there are cases of packet loss of the ping LAN IP and lf later there is connection, it is possible that the system is attacked by ARP. To verify the situation, we may judge by checking ARP table. Enter the ARP -a command as illustrated below. It is found that the IP of 192.168.1.1 and 192.168.252 points to the same MAC address as 00-0f-3d-83-74-28. Evidently, this is a cheat by ARP. 3. ARP Solution Now we understand ARP, ARP cheat and attack, as well as how to identify this type of attack. What comes next is to find out effective prevention measures to stop the network from being attacked. The general solution provided by Qno can be divided into the following three options: a) Enable “Prevent ARP Virus Attack”: Enter the device IP address to log in the management webpage of the device. Enter ”Firewall-> General” and find the option "Prevent ARP Virus Attack" to the right of the page. Click on the option to activate it and click "Apply" at the bottom of the page (see illustrated). 31 SSL / IPSec VPN QoS Router b) Bind the Gateway IP and MAC address for each PC This prevents the ARP from cheating IP and its MAC address. First, find out the gateway IP and MAC address on the device end. On every PC, start or operate cmd to enter the dos operation. Enter arp –s 192.168.1.1 0a-0f-d4-9e-fb-0b so as to finish the binding of pc01 as illustrated. For other host devices within the network, follow the same way to enter the IP and MAC address of the corresponding device to complete the binding work. However, if this act restarts the computer, the setting will be cancelled. Therefore, this command can be regarded as a batch of processing documents placed in the activation of the operation system. The batch processing documents can be put in this way: @echo off arp -d arp -s Router LAN IP Router LAN MAC For those internal network attacked by Arp, the source must be identified. Method: If the PC fails to 32 SSL / IPSec VPN QoS Router go online or there is packet loss of ping, in the DOS screen, input arp –a command to check if the MAC address of the gateway is the same with the device MAC address. If not, the PC corresponding to the MAC address is the source of attack. Solutions for other device users are to make a two-way binding of the IP address and MAC address from both of the PC and device ends in order to carry out the prevention work. However, this is more complicated because the search for the IP and address and MAC increases the workload. Moreover, there is greater possibility of making errors during the operation. c) Bind the IP/MAC Address from Device End: Enter “Setup” under DHCP page. On the down right corner of the screen, there is “IP and MAC Binding,” where users may create IP and MAC binding. On “Enabled,” click on “√” and select “Add to List.” Repeat these steps to add other IP addresses and MAC binding, followed by clicking “Apply” at the bottom of the page. 33 SSL / IPSec VPN QoS Router After an item is added to the list, the corresponding message will be displayed in the white block on the bottom. However, such method is not recommended because the inquiry of IP/MAC addresses of all hosts creates heavy workload. Another method to bind IP and MAC is more recommended because of easy operation, reducing workload and time efficiency. It is described in the following. Enter “Setup” under the DHCP page and look for IP and MAC binding. On the right, there is an option of "Show new IP user" and click to enter. 34 SSL / IPSec VPN QoS Router Click to display IP and MAC binding list dialog box. In this box, the unbinding IP and MAC address corresponding to the PC are displayed. Enter the "Name" of the computer and click on "Enabled" with the display of the “√” icon and push the option on the top right corner of the screen to confirm. Now the bound options will display on the IP and MAC binding list (as illustrated in Figure 5) and click "Apply” to finish binding. 35 SSL / IPSec VPN QoS Router Though these basic operations can help solve the problem but Qno's technical engineers suggest that further measures should be taken to prevent the ARP attack. 1. Deal with virus source as well as the source device affected by virus through virus killing and the system re-installation. This operation is more important because it solves the source PC which is attacked by ARP. This can better shelter the network from being attacked. 2. Cyber café administrators should check the LAN virus, install anti-virus software (Ginshan Virus/Reixin must update the virus codes) and conduct virus scanning for the device. 3. Install the patch program for the system. Through Windows Update, the system patch program (critical update, security update and Service Pack) 36 SSL / IPSec VPN QoS Router 4. Provide system administrators with a sophisticated and strong password for different accounts. It would be best if the password consists of a combination of more than 12 letters, digits, and symbols. Forbid and delete some redundant accounts. 5. Frequently update anti-virus software (virus data base), and set the daily upgrade that allows regular and automatic update. Install and use the network firewall software. Network firewall is important for the process of anti-virus. It can effectively avert the attack from the network and invasion of the virus. Some users of the pirate version of Windows cannot install patches successfully. Users are advised to use network firewall and other measures for protection. 6. Close some unnecessary services and some unnecessary sharing (if the condition is applicable), which includes such management sharing as C$ and D$. Single device user can directly close Server service. 7. Do not open QQ or the link messages sent by MSN online chatting tools in a causal manner. Do not open or execute any strange, suspicious documents, and procedures such as the unknown attachment enclosed in E-mail and plug-in. 4.
